SPECIFICATION forming part of Letters Patent No. 511,813, dated January 2, 1894.

Application filed $eptember 25, 1893- Serial No. 486,383. (No model.)

To all whom) it may concern.-

Be it known that I, KARL M. STAHL, of New York city, New York, have invented an Improved Smoke-Oonveyer for Railway-Oars, of which the following is a specification.

This invention relates to a novel construction of that kind of conveyer, which is adapted to conduct the smoke and products of combustion directly from the stack of the locomotive, over the roofs of the cars, andto discharge it at the rear end of the train.

In the accompanying drawings: Figure 1 is an elevation partly in section of a train provided with my improved conveyer. Fig. 2 is a side view partly in section of the conveyer; Fig. 3 a top view partly in section of the same. Fig. 4 isa similar view, showing the position of the conveyer on rounding a curve, and Fig. 5 is a vertical section through the upper part of the smoke stack.

The conveyer is composed in effect of two side plates at, a top plate b, and a bottom plate 0, the whole constituting a horizontal flue on the top of each car A. The sides a, a, are provided at each end with two pair of toggles a, a which permit the conveyer to round a curve (Fig. 4). To the outer toggles 0. there are in turn pivoted the coupling hooks a A spring (1, connected to a cross arm (1', and to the rear of hook a tends normally to interlock the hooks, while a spring 61 connected to the cross arm 61, and to the front of the hook a tends to hold the conveyer in a straight line. At or near the center each plate a, is provided with an opening and within this opening there is pivoted centrally a valve e, bent outward at both ends. This valve will be automatically operated by the air draft as the train moves in either direction, so that the air rushes from the front to the rear of the train and draws the products of combustion along with it.

The top and bottom plates Z), c, are constructed one like the other. They are each divided between the toggles a, a and are there provided with laterally extending overlapping wings, marked 1), 0, respectively, that permit the conveyer to be distended or to round a curve (Fig. 4), without creating an opening between the plates. At their ends and between the hooks a the plates 1), o, are provided with beveled contact edges as shown. Beneath and above such contact edges, pivoted, overlapping extensions 6 0 are secured to the plates, which prevent an opening from being formed at the coupling, in case of vertical displacement.

The stack f, of the locomotive is curved and is made of a cross-section to readily connect with the conveyer. It is provided with a valve f, that permits the products of combustion to be either directly discharged, or to be conducted to the end of the train through the conveyer.

It will be seen that my conveyer is always closed at the joints, while no flexible material is employed in its construction.

WVhat I claim is-- 1. The combination in a smoke conveyer of side plates a, having toggles a, a and hooks a with cross arm at, springs d d connected .,t0 the cross arm and to the hooks, and with a top and a bottom plate, substantially as specified.

2. The combination in a smoke conveyer of side plates (1, having toggles a, a and hooks a with sectional top and bottom plates b, 0, having laterally projecting wings I), c, and forwardly projecting pivoted extensions b 0 substantially as specified.
